Spinach Mushroom Quiche

Bill will eat Quiches if I call it pie. He’s one of those holdovers from the “Real Men Don’t Eat Quiche” era. Of course, I had to marry a real manly man. Sigh. Boy, did the kitchen smell incredible while this was baking. I could hardly wait to dig in. When I make omelets, I always add spinach and mushrooms, so it’s not a stretch to see why I chose these two for this Easy Quiche Recipe. To add some color, I diced a bit of red bell pepper to add to the vegetable mixture. Totally optional, of course.

Tips for How to Make a Quiche:

You can tweak this Easy Quiche Recipe however you’d like.

Keep the amounts of eggs, cheese and half and half and cream the same, but add bacon, ham or your favorite vegetables. PRO-Tip: But for the BEST results, don’t overload with fillings. Part of the deliciousness of this quiche was having the perfect ratio of egg custard to filling.

Saute your vegetables before adding them to the crust. Mushrooms, for example, will taste much better when cooked first.

Use your favorite shredded cheese or combination of cheeses like sharp cheddar, mozzarella, Gouda, Monterey Jack. The options and combinations are endless.

If you’d like a meaty quiche, adding cooked and crumbled sausage or cooked and diced bacon would be delicious.

Feel free to use your favorite pie crust recipe or store-bought crust for any of your quiches.

To check for doneness, insert a knife into the middle of the quiche. It should come out clean but be careful not to over-bake or the eggs will become rubbery.

I served this Spinach Quiche for a meatless dinner recently. When the hubby came home from work, he reminded me, “I don’t really like quiche.” Sigh. When he finally decided to have a slice instead of a peanut butter sandwich, he did admit, “This is pretty good.” I consider that a victory. I found it to be my best quiche ever. The ratio of eggs and creams made for the perfect textured quiche, and one I will make again and again.

What is quiche made of?

A basic quiche is made of a milk and egg custard poured into and baked in a pie shell. Many variations, including the classic Quiche Lorraine, have additional ingredients. For a quiche Lorraine, there is also Gruyere cheese, bacon, and onion added to the custard.

Can you freeze quiche?

Yes, a quiche can be frozen. It’s easiest to freeze after baking, just let cool, then slide into a freezer-safe bag, and seal. Quiche is best frozen for up to a month.

What is the difference between a quiche and a frittata?

Reheat the quiche on a baking tray at 350 degrees for 30-35 minutes or until the middle reaches an internal temperature of 160 degrees.

Can you make a quiche the night before?

The crust could get soggy sitting overnight, but you can prep much of the recipe the night before. The vegetables can be sauteed, the crust made and ready to roll out, and the custard whisked together. Using a store-bought crust makes the process even simpler!

If you must make the quiche the night before, partially bake the crust before adding the custard. This gives a little more stability to the crust when you add the fillings and bake. A sprinkle of cheese over the bottom crust after par-baking will also shield the crust from any absorption of the custard. Do this just after pulling it out of the oven so the cheese has a chance to melt.
